Crowly: Automated A/B Testing vs Singleton | Verify Customersfor Shopify (2026)
Crowly: Automated A/B Testing and Singleton | Verify Customers are both 5-star rated apps on the Shopify app store in 2026, but they serve drastically different purposes. Crowly aims to boost revenue through automated A/B testing of product descriptions, pricing, and more, targeting merchants focused on conversion rate optimization across their entire product range. It positions itself as an AI-powered solution that simplifies A/B testing, offering different automation levels and compatibility with all store types. Singleton, on the other hand, focuses on customer verification and access control. It empowers merchants to validate registered customers, allowing or disallowing them to see prices and "add to cart" buttons. This app targets merchants who need to restrict access to their store based on customer status, perhaps for wholesale pricing, membership programs, or regulatory compliance. The app allows custom fields and customer tagging for advanced management. The primary difference lies in their core functionality: Crowly is about increasing conversions, while Singleton is about controlling access.
